  1. * Pearson's coefficients of correlation; the coefficients in bold characters are those that met our a priori predictions regarding their direction and magnitude (see text).
  2. † Non significant correlation
  3. ‡ p ≤ 0.01
  4. § p < 0.05
  5. Note: The negative coefficients of correlation obtained with the BMI and the BDI are from the higher scores on these measures indicating worse quality of life.
